It was difficult ride, but I ended it. May be with original Ender 3 S1 Pro it could be easier, but I transformed it with help of Sonic Pad. As a result I found problematic of print with prusa slicer, but in Ender and Cura slicers the result was not so good. Moreover the red plastic is strange - it looks like combination of pla and tpu. After some investigation and with help of Orca slicer it printed nice. Moreover, at this time all supports in most case very easy to remove - one just needs to find right direction of removal. Only one part should be removed with precision - back of letter Y. It is too thin. I used double sided scotch to do it more strong. Hope, to present it on my wife birthday.
